CLARENCE SCI-100K, OF MOUNT JOY, PENNSYLVANIA.

FOOD-CHOPPER.

Specification of Letters Patent.

Patented Feb. 2st, 1914.

Application filed May 21, 1912, Serial No. 698,708. Renewed July 8, 1913. Serial No. 777,962.

To all whom it may concern:

Be it known that I, CLARENCE SOHOGK, a citizen of the United States, residing at Mount Joy, in the county of Lancaster and State of Pennsylvania, have invented oer-- tain new and useful Improvements in Food- Choppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to ma e and use the same.

This invention relates to choppers, and it more particularly relates to food choppers of the same general character as the food chopper illustrated and described in my copending application #694,318 filed May 1, 1912.

An object of the present invention is to provide certain improvements in the construction of the cutting disks, for rendering the same more durable, economical and efficient.

Another object of the invention is to provide a more perfect and substantial bearing for the feed worm.

Other objects and advantages may be recited hereinafter and in the claims.

In the accompanying drawings which form a part of this application, Figure 1 is a perspective view of the complete chopper. Fig. 2 is a fragmental sectional view through the cutting disks and their adjuncts, and, Fig. 3 is an elevation view of the cutting disks in position upon the end lug of the worm,

Referring to the drawings in which similar reference characters designate corresponding parts throughout the several views, the hopper 1, the barrel 2, the standard 3, and the clamp arm 4 constitute the body or frame of the chopper, a worm 5 being rotatable within the barrel, by means of a crank 6. A movable clamp member 7 is provided for securing the frame to a shelf or table, all substantially as shown and described in said co-pending application.

A pair of flanged cutting disks 8 and 9, respectively, are provided with peripheral flanges 10, for adding rigidity thereto. The disks 8 and 9 are provided with eccentrically disposed series of apertures 11 and 12, respectively, and with central apertures 13 and 1 1, respectively. The disk 8 is provided with an annular and cylindrical flange 15 which fits within an annular flange 16 of the disk 9 as shown in Fig. 2.

The peripheral flange of the disk 8 fits around the end of the barrel 2, said barrel being provided with a shoulder 17 against which a stop lug 18 of the disk 8 is seated, for preventing rotation of the disk 8 upon the barrel. The disk 8 is seated on the retaining lug 19, and rests against a shoulder 20, at the junction of the retaining lug with the body of the feed worm 5, in such relation that the axis of thb disk is concentric with the axis of the feed worm. It will be noted that the retaining lug 19 comprises two oppositely disposed arcuatc surfaces 21, and two flat peripheral surfaces 23, the arcuate surfaces 21 being rotatably seated within the annular flange 15. The lug 19 extends through the flange 15, into a central aperture 24, of a yoke 25, said aperture conforming to the surface of the lug 19. The yoke 25 may be secured on the lug by any proper means, such for instance as a screw 27, which extends through a central aperture of the yoke and engages with the hag 19, as shown. The flange 16 is rotatably seated upon the flange 15, and is adapted to be rotated thereon by means of a stop lug 28 which abuts against a radial extension 29 of the yoke 25.

The yoke 25 is provided with an annular recess 26 into which the flanges 15 and 16 extend, and which coacts with the flanges 10 and 16 for retaining the disk 9 in fixed and rigid relation with the yoke 25.

By means of the disks 8 and 9 and their concentric peripheral and annular flanges, the worm 5 is positively and permanently retained in concentric relation with the barrel 2 by means of the flange 10; the worm 5 and the disk 9 are held in concentric relation to each other and to the barrel, by means of the flange 14, and the yoke being seated upon the disk 9 and being rotatable with the worm 5, is adapted to rotate the disk 9 therewith, and because the eccentric apertures and the cutting edges thereof, are alternately brought into and out of registration with those of the disk 8. It is obvious, from the disclosure in Fig, 2, that by tightening the screw 27, the contacting surfaces of the disks 8 and 9 are drawn more tightly together. It is also obvious, that because of the concentric and inter-joining flanges l5 and 16, extensive bearing surfaces are provided, for minimizing the wear and thereby prolonging the term of utility of the chopper.

It will be seen that I have provided new and useful improvements in devices of this character, such improvements being fully capable of attaining the foregoing objects, and in a thoroughly practical and eflicient l'nZtnIlGI'.

I do not limit my invention to the exact details of construction, combination and arrangement of parts as herewith described and illustrated, but my invention may only b limited by a reasonable interpretation of the following claims.

What I claim is:

1. In a food chopper, a retaining lug, a disk having a concentric aperture and eccentric apertures, an annular flange extending from the surface of the disk adjacent to the central aperture and forming a bearing for the retaining lug, a second disk having eccentric apertures and a concentric aperture and having an annular flange adjacent to the concentric aperture and forming a bearing around the first said annular flange, and means coacting with the retaining lug for rotating the last said disk so as to bring the eccentric apertures of the last said disk alternately into and out of regis tration with the eccentric apertures of the first said disk.

2. In a cutter mechanism for a food chopper, a disk having a central aperture and a cylindrical flange adjacent to the aperture, said disk being non-rotatablv mounted, a second disk having an annular flange rotatably mounted upon the cylindrical flange of the first said disk, said disks having cutting edges adapted to be brought into and out of registration when the rotatable disk is rotated.

3. In a cutter mechanism for a food chopper, a pair of cutting disks concentrically mounted and held in concentric relation by means of inter-joining and concentric flanges, said disks being fitted upon a rotatable member, one of said disks being held against rotation, a yoke secured to the rotatable member and having means thereon for causing one of said disks to rotate therewith, said yoke having an annular recess into which the interjoining flanges extend.

4. In a cutter mechanism for a food chopper, a barrel, a feed worm rotatably mounted in the barrel and having a yoke secured in fixed relation thereto, said yoke having a circular recess concentric with the barrel, an cccentrically apertured disk having an annular flange closely fitted into the re cess of the yoke and being mounted to rotate with the yoke, said feed worm having a shoulder, a second eccentrically apertured disk seated against the shoulder and having an annular flange extending into the an nular flange of tie first said disk, the last said disk being non-rotatably mounted.

5. In a cutter mechanism for a food chop per, a barrel, a feed worm rotatably mounted in the barrel and having a yoke secured in flXed relation thereto, said yoke having a circular recess concentricwith the barrel, and an eccentrically apertured disk having an annular flange fitted into the recess of the yoke and means near its periphery for engagement with a portion of the yoke, whereby said worm, yoke and disk may be rotated together.

6. In a cutting mechanism for a food chopper, a pair of centrally apertured disks each having a bearing flange formed around its central aperture and having cutting edges between its flange and its periphery, said bearing flanges being journaled together in relatively rotatable relation, and means engaging with the said disks ter pressing the cutting edges in operative contact.

7. In a food chopper, a plurality of juxtaposed cutting disks rotatable relative to each other, one of said cutting disks being provided with a cylindrical flange which constitutes a bearing, and a second cutting disk having a cylindrical flange forming a journal, said journal being rotatable in said bearing, and means for rotating one of said disks.

8. In a food chopper a metal cutter having a central cylindrical bearing flange, and a second cutter rotatable on said flange to cooperate with the first said cutter to chop the food.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
